Why marinade meat with acid or enzymes?

This might sound like a queer question, but why do we marinade meat with acid / enzymes? Given that marinading doesn't tenderize meat, it just turns the outer fibers into mush and releases the juices when cooking? Why not just go with a flavored brine instead?
In other words: Why is it customary to use such marinades, and why is it commonly said that it tenderizes the meat?

At first, water molecules are attached to and trapped within this protein mesh, so the tissue remains juicy and tender. But after a short time, if the protein is in a very acidic marinade, the protein bonds tighten, water is squeezed out, and the tissue becomes tough. If you've ever tried marinating shrimp in highly acidic ingredients, it's likely that you're familiar with this result.

My experience with tenderizing enzymes mirrors that of Dr. Nicholas Kurti, a famous Oxford physicist who tried tenderizing a pork roast by injecting half with pineapple juice, leaving the other half untouched. A noted chef, Michel Roux, was to judge on television which side was better. After cooking, the half treated with pineapple was total mush and looked like a pile of stuffing. Not surprisingly, Chef Roux preferred the untreated half.

Hardly a queer question. We marinate in acidic liquids because it tastes good, really. As Alton Brown said in the Good Eats episode, "Raising The Steaks":
"Acid doesn't tenderize meat nearly as well as enzymes. But acids can help you tenderize your own food. That's because acids taste tangy, and tangy tastes tell our saliva glands to do their stuff, and saliva is full of enzymes."
As that same episode shows, we generally don't marinate in enzymes, as it would turn meat to mush, and not in a good way.

What is the purpose for marinating meat in an acidic solution?
In "Kitchen Science," Howard Hillman explains that this is because the acidic ingredients diminish a meat's ability to retain moisture. Hillman notes that the increased flavor more than compensates for the loss of juice. Marinades also are used to add flavor to meats.Does acidic marinade tenderize meat?
Acid won't have any effect on the tenderness of meat one way or another. If you marinate a piece of meat in an acidic liquid for a long time, those acids will cause the surface of the meat to take on a mealy, mushy texture. This undesirable effect should not be confused with tenderizing.What is the importance of acids components in making marinade?
Acids work in multiple ways to help flavor penetrate meat. Acids help break down the connective tissue in meat, which can slightly tenderize the meat and allow deeper penetration. An acidic flavor component is also important for balancing a flavor profile.When meat is to be marinated using acids what should be used?
